Selected discourse behaviors of children with specific language impairment (SLI) presenting expressive (E:SLI) or combined expressive-receptive deficits (E-R:SLI) were compared to each other and to chronological age-mates and younger mean length of utterance (MLU)-matched children with normal-language skills. The two SLI subgroups varied from each other on specific measures of turn-taking and cohesion. These findings imply the need for future normative work with SLI subgroups differing in receptive skill, and indicate that, in the interim, pragmatic research with this population will need to consider potential effects of receptive language status when interpreting variations in outcomes for discourse-based variables.
将患有特定语言障碍（SLI）的表达性语言障碍儿童（E:SLI）或表达-接受性综合缺陷儿童（E-R:SLI）的特定话语行为，与同龄儿童以及语言能力正常、平均语句长度（MLU）匹配的年幼儿童进行了比较。这两个SLI亚组在轮流发言和连贯性的具体指标上存在差异。这些发现意味着未来需要针对接受技能不同的SLI亚组开展标准化研究，并且表明，在此期间，针对这一群体的语用学研究在解释基于话语的变量结果差异时，需要考虑接受性语言状态的潜在影响。
